'As stated, the bobbins lie loosel'y in suitable pockets. two of which pockets are provided to every running (aetire) thread, one -to con tain the bobbin of the active thread and the other that of a reserve thread. Reserve threads sueeeaaively become active threads, and for this reason eaeli Of'ille twopoekets eontainfi the bobbin of an a'etivethitead and that/of a reserve thread alternately.

Figs. 2; and 22' are side elevations of the. ram e \'linder and the tying-bill, showing said tying-bill in different positions Fig. ll is an edge view of a spring for the extends forwardly between the threadclamping fingers 34, said clamping fingers being moved during the operation of the mechanism to clamp the threads between said clamping fingers and the hook of the tln'ead-holding arm.

A spring 39 coiled about the hub 29 is attached at one end to the arm 31 and at the other end to the threadholding arm 36, and by reason of its elasticity tends to hold apart said arm 31 and the threadholding arm 36. A stop pin it) fixed upon the arm 17 limits the forward or spring-caused movement of the thread-holding arm 36. A spring latch 41 is pivotally mounted upo the tln-ead-lmlding arm 36, which latch adapted to engage the angular upper end oi the pin 35. by which engagement the threadholding arm 36 and the bell-crank arm 31 are locked together. The integral arm 42 ot the latch 41 also has a downwardly extending trigger pin 43, which projects through an opening 44 in the arm 36 and is adapted to engage the delay-stud 5 on the arm 17. The delay-stud 45 limits the rearward movement of the arm 36 through the medium of the trigger pin 43.

The integral arm 42 of the latch 41 is adapted to be engaged by a flat spring 46 (Fig. it) to hold the latch ina position to engage the angular stud 35. said spring normally holding the pin 43 against one end wall of the opening 44. The form of the spring 46 is such that it is held in position without extraneous securing means. The body portion of said spring is bent over upon itself, forming the spring clamp 47. by

means ol' which clamp the spring is firmly held upon one end of the arm 36. the ear -43 preventing vertical displacement of the pring.

The operation of the knot-tying mechanism is as follows: A rotation of the actuating wheel 125 communicates rotatory motion to the knottershaft 18 by means of the skew-gum connection between said actuating wheel and said shaft. The arm 36 having the antil'rietion roller 32 lying within the wave-cam-groove 15 of the act ating wheel 13. is also positively moved, as is the bellcranl\' arm Ill and the thread clalnping arm 3:1 pivotally secured to said arm. The thre=nl-holding arm 36 is moved by the cam only when its latch ll engages the stud on the bell-crank arm 31. When the latch ll engages said stud the thread-holding arm is drawn back. swinging outward upon its pivotal bearing away from the tying-bill, which movement is to tighten the knot and strip the thread from the bill. As soon as the latch 41 is disengaged from the stud 35, the spring 39 swings the arm 36 against the stop pin (Fig. 16), said arm sliding between the clamping fingers 34. During the rotation of the tying-bill the thread-clamping fingers 34 are moved forward upon the thread-holding arm 36, reaching the hook at its forward end and clamping the thread in said hook immediately after the necessary thread to form the loop of the knot has been wound upon the rotating tying-bill. The knot-tying mechanism just described is also shown in my former Patents Nos. 672,636 and 755,110.

Each of the knotter carriages 5 is provided with a bracket having a cam-groove 50. (Fig. 13) and with a restoring shoe 51, the purpose of which groove and shoe will appear later herein. The two sides 2 and 3 are identical but oppositely arranged; one of them will next be described. The side 2 comprises a longitudinally extending front bar 52 (Fig. 3) and rear bar 53. A little distance forward from the tront bar 52 is an air tube 54 for receiving the ends of exhausted threads. and adjacent to this air tube is an air tube 55 for receiving the ends of the reserve threads. Forward ot' the air tubes 54 and 55 is a roller 56 rotatably mounted in the supporting frame. extending the full length of the side, and provided in its face at intervals throughout its length with V-grooves 57. Just forward of the rear bar 53 a similar but slightly smaller roller 58 is rotatably mounted. also provided with V-grooves 5 each alined with one Of the similar grooves in the roller 56. The rollers 56 and 55 are driven by a belt (not shown) passing over the sheave 61, (Fig. :3) and by a belt 63 running over the sheaves 63 and 64. The peripheral speed of the roll ers 56 and 5% is greater than the winding speed: said rollers do not. however. positively feed the yarn to the warp beam. but

merely tend to do so, and thus serve to reduce the tension of the thread. The roller 56 reduces the tension of the yarn in the region between said roller and the guide 7! Said guide and the eye 65 increase the tension somewhat. above that existing between the roller 56 and the guide. but the tension is st ill further reduced by the roller 58. The purpose of the rollers 56 and 58 is tc insure that the greatest tension shall be in .he re gion between the bobbin and the roller 56. in order that any yarn breakage shall occur in this place.

Any suitable form of bobbin-holder may be used for supporting the active and the reserve bobbins. llerein l have shown pairs of bobbin-holders or pockets 66 and 67 attached to the frame member 65, one bobbinholder of each pair being below the other. A separating shield 68 extends upwardly from each pair of bobbin p0ckets,each shield being in the vertical plane of one of the V- grooves 57. The bobbin pocket 66 opens on one side of the shield 68, and the pocket 67 is at. the other side, so that the active and the reserve threads of each pair of bobbins are separated by said shield. These threads are further guided from their huhhins by th fingers (32) and 70 for (he pm-kuts G7 and (H3. rcs mviiwly.

The restoring shoe 51 returns the detent pin to its forward position, as indiiated in Fig. 11. This 'iseillatory restoring movement of the shaft 93 is cominunieated by means of the ronneeting rod it to the deteetor shaft 3. oseillating said shat't. raising the arms St. 88 and S9 in the position shown in Fig. 11. and windrawing the elamping finger 37 from engagement with the formerly exhausted but now artive thread. The slaek tn'odueed in the united threads by the casting off of said threads by the knotter, as well as the slat'k produced by the rising 'ot' the deteetor St. is taken up by the rider H2. The normal tension of the thread being restored. the deter-tor R4 is held upward in the horizontal position shown in Fig. 11 against the downward tendeney ol' the eoiled spring 86. During the time occupied by the tying oper ation, and while the end of the exhausted thread was held by the elamping linger R7, the winding ineehanisni was supplied with thread from the loop Til". drawing the riden weight 8; at the bottom of said loop upward within the guide ehannel St). .\s soon as the exhausted thread again beeomes a wtiw the rider-weight gradually sinks. until it rearhes a suitabte stop. as. for example. the'lioor. thus aeeuniuhiting sla lt in the loop 7:. f itop pins no tl igs.

To stop said gear at proper intervals. a pawl 10o (Figs. 12 and 15) is provided. whieh pawl is adapted to enter notehes 101 in said aetuating gear. The pawl is mounted upon a shaft M12. and is held in yielding eontaet with said aetuating wheel by means of a roiled spring 10?) extending between a erank arm 104 on said shaft and a fixed point on the knotter earriage .3. her the aetuation of the tying mechanism. the waste ends of the exhausted and reserve threads are drawn into the ail tubes 5t and respedtively. and removed by the air eurrent within said tubes.

in operation. power is supplied to rotate the chain wheels 7 to trawl the knotter earriages 5, to drive the means for producing an air current in Cilt'll of t" ttubes 34 V and 55, and to operate the winding meehanisni 8. Full bobbins are placed within the pockets 66 and G7, the thread from one bobbin being drawn up ard by the operative by the side of the separating shield 8 into the gmove 37 ot' the forward roller 513, forwardt tlll'Otlgll the slit 74 in the upper part of the air tube fit. over the guide finger 79. through the eye of the detector arm H. upward into the groove .39 of the roller .38. downtard from said roller into the guide 'hanne '80, through the riderwveight 2. rpwart? hrough the guide ehannel. through the eye 1. and from theuee to the winding meehanism.
